[R] Generating all possible partitions

I have posed this question earlier, however it has probably not been clear 
enough.



My problem is such. I would like to find all possible partitions of a set of 
n objects into k groups. The ordering of the groups does not matter, only 
which objects are together matters.



For example, there are two possible partitions of 3 objects into 2 groups:

1 1 2

1 2 2

By "the labels are not important" I meant that a partition 1 1 2 is 
identical to the partition 2 2 1.


Best regards,

Ales Ziberna
